Abstract

The invention provides ketotifen fumarate tablets. The ketotifen fumarate tablets are prepared by adopting superfine grinding technology and tablet process technology and are high in dissolution rate, lasting in action, few in administration times, stable in blood-drug concentration and higher in safety, and treatment effect of the ketotifen fumarate tablets is brought into full play.

Description

technical field [0001] The invention relates to a ketotifen fumarate tablet and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] Ketotifen (Ketotifen) is an oral potent allergic transmitter release agent, commonly used as its fumarate, and is an anti-allergic drug. The drug can not only inhibit the antigen-induced release of histamine and allergic slow-response substance (SRS-A) from mast cells in the lung and bronchial tissue, but also inhibit the induction of eosinophils or neutrophils by antigens, serum or calcium ion transmitters. Slow-reacting substances that release histamine and allergies. The drug has a strong H1 receptor antagonistic effect and can antagonize 5-hydroxytryptamine and allergic slow-response substances. Studies have found that the drug can inhibit non-specific airway hyperresponsiveness in patients with bronchial asthma, and antagonize bronchospasm caused by allergens, histamine, carbo...
